just a quick question for you.if you coat the middle of the buttjoint
once.then you pull each side.doesnt that mean you actually only second
coated the paper.not tryin to knock your method at all.just curious.i coat
the middle and sides at the same time then repeat when dry.that way there
are two coats on the tape.and doesnt the 100 grit scratch the joints?or are
you usin green usg? i finish with proform and sand with 220 grit.

Never sand dw compound with 100grit, not even if you put too much mud on .
You can tell by the ‘spots’ that the vid maker’s a hacker. You never sand
butt joints until absolutely need to, and it’s with 150grit max. or worn
down 120g. And sanding these butts is done with a manual pole sander or
hand sander, for smoothness, or production electric. Sponge sander (fine
coarse) is for angles, used gingerly.

@synon9m Unfortunately the tape is used for a reason, it sure does make it
hard for amateur DIYers. The tape can prevent cracks from forming on all
your joints through the mud and paint. I wish the last person that owned my
house new that!

I frick’n hate drywall taping and painting b/c there is no hiding from
mistakes. This video cautions against sanding through the tape. Why tape at
all? Why not just spackled the hell out of it? I wish someone would invent
a different system for amateurs!

lines and jagged edges. -No mask!? FAIL -MY GOD your screws are coated 10
miles thick… -Use a POLE SANDER FIRST MY GOD, YOU’LL BE THERE FOR DAYS
